Since January, rumors of a new iPhone 5S-like device have been widely reported, but it was unclear how the technology giant could shoehorn it between the iPhone 6S and highly anticipated iPhone 7 campaigns. The solution, 9to5Mac reports, is a special, number-free edition called the iPhone SE.

The iPhone SE would have a 4-inch screen, similar to the old iPhone 5S but with curved edges and up-to-date hardware, the blog said. That's in contrast to screens after the iPhone 5 cycle, which moved toward "phablet" size at 4.7 inches and beyond.

Apple declined to comment to CNBC.

The details will become more clear in March when the tech giant will reportedly hold an event to launch a slew of new devices, according to 9to5Mac.
